摘要: Noncontact atomic force microscopy (AFM) has recently progressed tremendously in achieving resolution imaging through the use of small oscillation amplitudes and well-defined modification tip apex. In particular, it been shown that picking up simple inorganic molecules (such as CO) by AFM leads to a apex enhanced image resolution. Here, we same approach study three-dimensional intermolecular interaction potential between two focus on implications using molecule-modified tips for spectroscopy experiments. The flexibility CO at complicates measurement energy molecules. Our work establishes physical limits measuring interactions with scanning probes.
